One of the hotly anticipated titles of Xbox Live's Summer of Arcade is Trials HD, a physics-based motorcycle racing game, and the first complete trailer is now available.

I was able to demo Trials HD when I was at E3, and if you loved Trials 2 on Steam, you're going to love this. The game has 50 brand new levels, complete customization of the rider and bikes, tons of neat minigames to unlock, and best of all - a complete level editor, the same one they used to construct the game, and you can share them among friends.

Recently I was able to preview the game, brought some friends along, and the game became an instant smash hit. It is the perfect pass-the-controller game.

Look for it this August as a part of the Summer Of Arcade.
